Patent GB-965727-A (GB)
Title: Process for the treatment of leather,skins and hides
IPC: C14C9/00
Filed: 1962-08-29
Abstract: In the treatment of leather with polymerizing substances, there is incorporated into the leather an aqueous suspension having a pH of 6-8, and preferably 6.5-7.5, comprising an unsaturated polyester with an acid number of 10 or more, and one or more copolymerizable organic substances which does not contain an emulsifier, and copoylmerising in situ with the aid of a catalyst, preferably a Redox system.  The copolymerizable organic substance may be one or more of the compounds divinyl benzene, acrylic or methacrylic acid or their esters, preferably methyl methacrylate or styrene, or it may be a partial polymer.  In an example, a chrome-tamed skin was treated with a polymerizable mixture containing 70% unsaturated polyester resin (mixed with 40% of styrene), 18.5% monostyrene, 10.3% methylmethacrylate and 1.2% paraffin with the addition of 3% of benzoyl peroxide paste (50% in dibutylphthalate), the pH of the mixture first having been adjusted to 7 with KOH.  After 5 hours the amount of the mixture introduced into the leather was 30% based on the leather dry weight.  After rinsing, polymerization was initiated by treating for 1 1/2 hours with an aqueous accelerator liquor containing 0.4% by weight dimethyl-p-toluidine emulsified with castor oil, partially ethoxylated with ethylene oxide.  The leather contained 18% of polymer.ALSO:In the treatment of leather with polymerizing substances, hydrophilic characteristics in the treated leather are minimized by using an aqueous emulsion prepared by suspending an unsaturated polyester of acid number of 10 or more, preferably 10 to 20, in water, adding one or more organic substances that will copolymerize with it with the aid of a catalyst, e.g. an organic peroxide or Redox system, adjusting the pH of the suspension to a value between 6 and 8, preferably between 6.5 and 7.5, by adding organic bases or alkali, emulsifying the suspension before or after adding the alkali by stirring, no addition of emulsifying agents being necessary.  The leather is then rinsed with water and milled in a solution of a polymerization accelerator, or, alternatively, if the accelerator is incorporated in the emulsion, in a solution of the peroxidic catalyst, the latter then being omitted from the emulsion. The unsaturated polyester is produced by reacting polyvalent acids with polyhydric alcohols, either the acid or alcohol or both being unsaturated. Suitable copolymerizable substances include divinyl benzene acrylic or methacrylic acid or their esters and styrene, or a partially polymerized monomer.  The preferred ratio of polyester to copolymerizable substance is 3:2. Suitable Redox systems and polymerization accelerators are specified.

Upward and downward movement of a unit 36 due to large ground irregularities or use of a handle 122 causes a cam 120 on the rod 60 to engage and disengage a cam follower 118 which, through linkages 114, 106, 104, 102 causes members 86, 78 of the clutch 80 to disengage or re-engage respectively. The cutting units may be raised and lowered by piston-cylinder arrangements or cable-andpulley systems and a hydraulic clutch-operating device may replace the cam and follower mechanism. All the cutting units may be disengaged by a dog clutch and their relative positions may be varied.
Patent GB-1113004-A (GB)
Title: Production of methyl acetylene and allene
IPC: C07C5/48
Filed: 1966-07-25
Abstract: Methyl acetylene and allene are produced by pyrolizing propylene, e.g. at 950-1300 DEG  C., in the presence of a radical donor for combining with hydrogen produced during the reaction, suitable donors being oxygen, chlorine, bromine, diazomethane and allyl chloride. When allyl chloride is used it is itself converted to methyl acetylene and allene.  The methyl acetylene and allene produced may be separated by conventional techniques, or the product heated to isomerize the allene to further methyl acetylene.

Filed: 1928-11-20
Abstract: 323,869. Ellis, G. B., (Soc. des Usines Chimiques Rhone-Poulenc). Nov. 20, 1928. Cellulose butyrates.-Butyric esters of cellulose, including both butyric or iso-butyric esters as well as mixtures thereof, are prepared by tueating cellulose or its near transformation products, for example hydrocellulose or oxycellulose, or wood cellulose with butyric anhydride in presence of sulphonic acids derived from aliphatic hydrocarbons, for example methane or ethane suphonic acids, and preferably in presence of a solvent for the ester obtained, for example butyric acid, benzene, or monoehloracetic acid. Other catalysts employed in the acetylation of cellulose, for example sulphuric acid or zinc chloride, may be combined with the sulphonic acids. Improved results are obtained when the cellulosic material is pretreated, for example with butyric acid with or without a catalyst, for example methane sulphonic acid. The cellulose butyrates are precipitated from solution, for example by water or alcohol. The butyric acid may be recovered by fractional distillation of the water of precipitation and the methane sulphonic acid recovered almost integrally by completing the distillation under a good vacuum. The butyrates mav be employed for the manufacture of artificial silk, films, varnishes, and plastic masses similar to celluloid. Specification 161,564 is referred to.

Abstract: 980,720. Spinning shaft closure devices. FARBENFABRIKEN BAYER A.G. Aug. 29, 1963 [Aug. 29, 1962], No. 34267/63. Heading B5B. A closure device for a spinning shaft consists of a lid 3 hingeably connected at 4 (Figs. 2 and 4) to the lower edge of the spinning shaft 1 and provided with a continuous central bore and at least one funnel-shaped attachment on its under surface (7, Fig. 1, or 21, Fig. 3), the lid and the funnel-shaped attachment being provided with a longitudinal slit 8 extending through the lid and the wall of the attachment, locking members 10 and 10a engaging in grooves in the lid and swingable in a horizontal plane about the centre of the lid being arranged on the outside of the lid, a loose rotatable sleeve 9 (or 22, Fig. 3) covering the inner wall being arranged on the inside of the lid, the sleeve being provided with a continuous longitudinal slit 8 and connected at the bottom to the locking members 10, 10a, through stirrups 11. The locking members 10, 10a contain bolts 14 adjusted by compression springs 13 and provided at their ends, which are bent at right-angles with ball races 17, the outer rings of which run on to angle-pieces 18 which have inclined surfaces and are attached to the edge of the shaft, when the locking members 10, 10a are deflected. Stop spindles 20 limit the open and closed positions of the locking members 10, 10a. When members 10, 10a, and hence also the stirrups 11 are in the unlocked position, the slit 8 of the lid and of the funnelshaped attachment and of the corresponding sleeves (9 and 22) are in the same position and form a single gap in the whole apparatus, so that when the lid is deflected about the hinge 4 the spinning tow 23 can continue on its course without interruption since it passes through the slit 8 when the lid is deflected. When the lid is swung back and fitted on to the lower edge of the shaft by swinging the members 10 and 10a the tow 23 passes through the slit and is therefore not hindered in its course. At the same time that the lid is locked by swinging the members 10 and 10a in the direction of the arrows 24, the loose sleeve 9 is also rotated with them so that the longitudinal slit 8 in the lid and the attachment is covered. Thus the shaft is sealed against the outer atmosphere so that the temperature of the shaft, which must be kept constant, will not drop.
